logic:iterate problems
Hello All!
I'm running into some problems getting the
logic:iterate tag to work.
I have a class who's full name is
org.ellism.tir.util.DatabaseConstantsAdapter. It has
a public method, getInstance() that returns an
instance of itself (The class itself is a singleton).
This class has a method getProductLines() that returns
an ArrayList full of
org.ellis.tir.util.ProductLineToken objects. I'd like
to iterate over this collection and print some stuff
out.
I've tried this:
<%@ taglib uri="/WEB-INF/struts-html.tld"
prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld"
prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld"
prefix="logic" %>
...Lots of HTML code...
<logic:iterate id="productLine" collection="<%
org.ellism.tir.util.DatabaseConstantsAdapter.getInstance().getProductLines();
%>">
The name is: <bean:write name="productLine"
property="name"/>.
</logic:iterate>
However this doesn't seem to work, I get this error:
org.apache.jasper.JasperException: Cannot create
iterator for this collection
..Stack Trace
I'm not sure why this happens? The object returned by
org.ellism.tir.util.DatabaseConstantsAdapter.getInstance().getProductLines()
is of type ArrayList, and I thought that was a valid
collection to iterate over?
Any insights would be wonderful.
Cheers!

This worked as expected. It wrote:
java.util.AbstractList$Itr@c6e1ec to the HTML, which
leads me to belive that the collection is returning an
iterator.
I then tried this (after deleting the above):
<%
Collection c = ...getProductLines();
request.setAttribute("colName",c);
%>
<logic:iterate id="productLines" collection="colName">
Is this working?
</logic:iterate>
However, when I introduce the logic iterate tag, I get
the same "Cannot create iterator for this collection"
error.
I'd really like to not have to drop back to coding
Java to do the Iteration, since the taglib seems
cleaner to me.
Any ideas what to try?

Re: logic:iterate problems
Posted by guo yingshou <gu...@yahoo.com.cn>.
If i were you, i would check like this in my jsp:
<%@ page import="java.util.Collection" %>
<%@ page import="java.util.Iterator" %>
....
<%
Collection c = ...getProductLines();
Iterator it = c.iterator();
out.print(it);
%>
do not <logic:iterate> yet util the above code run
ok.And then you can be sure that the previous
<logic:iterate> should run with no problem.
the <logic:iterate> tag handler will always try to
retrieve the object from one of the 4 scopes ie.
page,request,session,application that you placed
sometime before.

Re: logic:iterate problems
Posted by Matt E <mg...@yahoo.com>.
Hello!
I tried that (I found I needed to change Collection c
to java.util.Collection c, so the compiler would not
complain) but I'm still experiancing the same problem:
org.apache.jasper.JasperException: Cannot create
iterator for this collection
I added some print statements to help me debug, and I
know that the getProductLines() method is being
called, so this *should* be working. I'm at a loss.
Here's the full stack trace if it will help anyone.
Thanks in advance for any insight anyone has.
Cheers!

Re: logic:iterate problems
Posted by guo yingshou <gu...@yahoo.com.cn>.
try something like:
<%
Collection c =
org.ellism.tir.util.DatabaseConstantsAdapter.getInstance().getProductLines();
request.setAttribute("colName",c);
%>
and then:
<logic:iterate id="..." collection="colName"...
</logic:iterate>
you can alse put your collection into the jsp scope
variable somewhere in your action.
hope it helps.
